You notice that some flour beetles have been living in a kitchen canister of "dry" flour for a year.As animals,beetles must have water for internal cellular metabolism,hemolymph,etc.How are they probably getting their water?

Question

Quizplus · Accepted Answer

The most likely way that the flour beetles are getting their water is through the breakdown of sugar (in this case, from the flour) into water and carbon dioxide through a process called cellular respiration. Beetles are able to conserve water by producing concentrated waste products, but they still require a source of water to survive. Cannibalism is not a reliable source of water and flying to a water source may not be possible for all beetles. It is also unlikely that they are able to recycle all of the water in their bodies, as this would be a very rare and specialized adaptation.
